Phys.org / Ancient Neanderthal genome reveals isolated, distinct populations
Neanderthals split into distinct regional groups that developed genetic differences far sooner than modern human populations typically did, according to a study published in Proceedings of the National Academy of Sciences. ...
Tech Xplore / New AI testing method flags fairness risks in autonomous systems
Artificial intelligence is increasingly being used to help optimize decision-making in high-stakes settings. For instance, an autonomous system can identify a power distribution strategy that minimizes costs while keeping ...
Medical Xpress / Reprogramming 'gatekeeper' immune cell may boost cancer immunotherapy
St. Jude Children's Research Hospital scientists have discovered how tumors disable immune "gatekeeper" cells that alert the rest of the immune system to the presence of cancer—and how restoring their energy production can ...
Phys.org / DNA-binding protein blocks virulence cascade in a diarrhea pathogen outside hosts, study finds
Some pathogens use temperature as a trigger and activate virulence only after entering the warmer environment of a host. A research team from Ruhr University Bochum, Germany, and the University of Münster, Germany, investigated ...
Medical Xpress / Study finds female veterans faced steeper well-being declines after COVID-19
While the COVID-19 pandemic challenged all veterans transitioning to civilian life, female post-9/11 veterans experienced a sharper decline in overall well-being compared to their male counterparts, according to new research ...
Phys.org / AI-driven framework uncovers new carbon structures—one thought to be harder than diamond
Through new improvements to existing AI models, researchers in China have created a framework that can methodically identify useful new forms of solid carbon. With their approach, Zhibin Gao and colleagues at Xi'an Jiaotong ...
Phys.org / AI turns electron microscopy into materials insights in minutes
An electron microscopy image can capture atoms arranged in a crystal lattice or defects threading through a semiconductor material, but turning that image into materials insight can take weeks of careful analysis. Now, an ...
Medical Xpress / Using augmented reality to motivate prosthesis training
Artificial limbs look and function more like real limbs than ever before—but that's only helpful if they are used as intended. One of the main reasons amputees give for not using their body-powered prosthesis is a lack of ...
Tech Xplore / Researchers measure traffic emissions, to the block, in real-time
In a study focused on New York City, MIT researchers have shown that existing sensors and mobile data can be used to generate a near real-time, high-resolution picture of auto emissions, which could be used to develop local ...
Medical Xpress / How pancreatic tumors thwart an iron-driven demise
Tumors driven by cancer-driving KRAS mutations are often susceptible to ferroptosis, a type of cell death that can be harnessed for cancer therapy. Given that more than 95% of pancreatic ductal adenocarcinomas (PDACs) harbor ...
Phys.org / Fins, fingers and toes: A new take on repeating body parts and how they come to be
As biologists know, nature can take its sweet time explaining itself. Andrew Gillis, associate scientist at the Marine Biological Laboratory (MBL), has been investigating how the paired fins of fishes evolved for nearly 20 ...
Phys.org / Nature's photocopiers caught 'doodling'—scientists say it could revolutionize how DNA is written
New research has discovered that the molecular machines responsible for copying our DNA have a surprising hidden talent—an ability to create entirely new and highly sophisticated DNA sequences from scratch. The study, led ...
